Abstract: 1,259,599. Plasma or flame spray coating. ASSOCIATED ENG. Ltd. 14 May, 1969 [15 May, 1968], No.23185/68. Heading B2E. A process for spray coating the internal surface of a pipe or tube by means of a gas plasma arc or a chemical flame includes rotating the pipe or tube at such a speed that the centrifugal acceleration acting on the sprayed particles when in contact with the internal surface to be coated is less than the acceleration due to gravity. When a plasma gun is used, the spray head of the gun is inserted into the tube and moved longitudinally while the tube is rotated, usually about a horizontal or vertical axis. An air blast may be directed towards the inner surface of the tube to blow away loose powder not adhering to the walls and thus falling down within the tube. When a plasma spray gun is used, some of the powder particles issuing therefrom may be fully melted.

Abstract: 1297712 Turbine power plant METALLGESELLSCHAFT A G 18 Aug 1970 [1 Sept 1969] 39775/70 Headings F1G F1Q and FIT  In a power plant a hydrocarbon containing liquid or gaseous fuel is cracked with steam and the resulting gas expanded through a turbine before being burnt in a combustion chamber. The fuel may be e.g. methane, ethane, butane, natural gas or refinery exhaust gas. If sulphur containing fuels are used the cracked gas is desulphurized before entering the combustion chamber. In one arrangement the cracking reactor 4 consists of a furnace filled with a nickel catalyst on a magnesia support. The reactor 4 is supplied with the fuel through line 1, with air from compressor 7 through line 2 and with steam tapped from turbine 12  through line 3. Oxygen or carbon dioxide may also be added. The gas resulting from the cracking reaction contains relatively high specified proportions of carbon monoxide and hydrogen and is expanded through a gas turbine 6 driving compressor 7 and generator 8 before passing through line 17 to the combustion chamber of steam boiler 11 where it is burnt with pre-heated air tapped through line 9. Steam from the boiler 11 flows through line 16 to drive turbine 12 and generator 14 before exhausting to condenser 13. In a modification, Fig. 2 (not shown) the cracked gas after expansion in the gas turbine (106) is burnt in a combustion chamber (112) and the combustion gases expanded in a further gas turbine (113) driving an air compressor (114) and generator (115). The exhaust gas from the further turbine (113) passes to a waste heat boiler (116), the steam from which is expanded through a turbine (118) driving a generator (120). In this arrangement the steam for the cracking reactor (104) is generated in a boiler (111) heated by the heat of compression of the air compressed in compressor (114). In a further modification, Fig.3 (not shown) the cracking reactor (204) is an externally heated tubular heater, the tubes of which are filled with a cracking catalyst such as nickel on an alumina support. Some of the combustion gases from the combustion chamber (207) are supplied to heat the reactor (204) and are thence passed to the steam boiler (211).

Abstract: 1304834 Antiskid systems HOPE TECHNICAL DEVELOPMENTS Ltd 6 Feb 1970 [6 Nov 1968] 52542/68 Heading F2F  In a vehicle braking system an antiskid device is provided having at least one sensing device 10 generating a pneumatic pressure control signal in dependence upon the rotation of a wheel and a plurality of multipath valves 19, 28, 29 controlling the braking pressure applied to an actuator 43 wherein at least one of the valves incorporating or having associated with it a timing device and having means for controlling its operative state in accordance with the signal so that braking pressure is cut off for a predetermined time interval when the signal indicates wheel locking. As shown the sensing device has a rotary element 10 frictionally engaging a brake drum 11 and is carried by a spindle coupled via gearing to a shaft 12 carrying a fan 13 supplying air to the device through conduit 16. The valves 19, 28, 29 each have two inputs 20, 21 or 34, 32 or 35, 33 and outputs 22, 30, 31 respectively, each valve being positioned in a first position, shown by dotted lines, by a control input such as 18 acting on control elements 23, 36 or 37 and in a second position, shown by a solid line, by a spring 25 or 40 or 41. In normal operation with the wheels rotating above a threshold speed, valve 19 is held in its first position connecting air reservoir 27 to the output 22 by way of input 20, valves 28, 29 also being held in their first positions. On braking, pressure passes from a line 42 to actuator 43 through valves 28, 29. If the wheels lock, spring 25 overcomes the control input pressure acting on control element 23 of valve 19 which is thus moved to its second position connecting output 22 to atmosphere via input 21. Valve 28 is also moved into its second position where output 30 is connected to atmosphere via input 34 but valve 29 is held in its first position for a predetermined time interval by the timing device (not shown) thereby relieving pressure in the brake cylinder 43 to relieve the locking, after which valve 29 moves to its second position. Braking is then restored by pressure passing to cylinder 43 by way of input 35 and output 31 of valve 29. In another embodiment the brake cylinders are more rapidly exhausted through a release chamber (61), Fig. 2 (not shown), which is connected to the output of valve 28 provided with two further inputs, and a further output the connection between which is controlled by the control element 38. In a further embodiment an adjustably vented capacitor is charged by the sensing device, a pressure drop in the capacitor indicating wheel locking and actuating multipath valves to provide an oscillating pressure to the wheel cylinders. The brake system proper may be hydraulic or pneumatic.

Abstract: 1312851 Shearing DAVY & UNITED ENG CO Ltd 19 April 1971 [4 Feb 1970] 5399/70 Heading B3W A reciprocatory shear, for progressively cutting through thick metal workpieces in a series of cuts, has hydraulic means for displacing at least one of the blades to a position in which the separation of the blades is equal to the thickness of a metal workpiece to be severed, drive means having a reciprocatory action and being coupled in one direction of reciprocating to one of the blade holders to move it towards the other blade holder through a distance which is small compared with said separation to cut partway through the metal workpiece and hydraulic means for keeping the blades in the same relative spaced position during movement of the drive means in the second direction of reciprocation. As shown, Fig. 1, a blade holder 14 is reciprocated by a rotary eccentric 17 and crosshead 16, or a pitman (not shown) acting through an hydraulic piston 18 and cylinder 20. The throw of the eccentric may be 1 inches when the maximum workpiece thickness is 14 inches. The cylinder 20 is connected through a pre-fill valve 27 to an accumulator 28 and through solenoid-controlled valves to a fluid supply 32. In use, the blade 12 is lowered on to a workpiece by further piston and cylinder units 22, 23. The eccentric is then rotated, the valve 27 closing to cause fluid in cylinder 20 to be sealed off. Drive of the piston 18 is therefore transmitted to the blade holder 14 and a cut is made partway through the thickness of the workpiece. During return of the crosshead 16 the valve 27 is open causing the piston 18 to rise also while cylinders 23 maintain the blase in contact with the workpiece. Further cutting cycles are carried out until shearing is completed after which the blade holder 14 is returned to its original position relative to the piston 18 by the piston and cylinder units 22, 23. In an upcut shear, Fig. 2, the drive member 62, 63 and piston and cylinder device 58, 61 are associated with the lower blade holder 57. The other blade holder is mounted on a piston 52 of a cylinder 51. In use, blades 53 and 56 are first moved to engage a workpiece by piston and cylinder units 54, 55 and 59, 60 respectively and the blade 53 is actuated similarly to blade 12. In a further embodiment (Fig. 3, not shown) the upper blade is the driven blade and the other blade is mounted on the piston of the hydraulic piston and cylinder device.
